- Start date
Upgrade to Java 1.4.1_03. Vers 03 has bug fixes and Sun says to use that version.
What network card are you using? There are incompatibilities between Java and certain network cards.
On the IB website there is a Technical FAQ page called
Compatible Network Cards.

This lists cards that work with Java. I can't find the list of offending cards any more. But there are cards that dont work so well with Java.
TWS and IB is not as touchy as you describe.

There are also some incompatibilities between ATI video cards and MS direct draw. Insert this code into the TWS startup string so that direct draw is not used.
There are other types of Java/MS/video card problems. Usually these problems involve freezing, crashing or crashing on exit.
no direct draw command-
Right click on the Trader Workstation icon and choose "Properties". Then click on the "Shortcut" tab. In the "Target" field insert the following code before the -jar
-Dsun.java2d.noddraw=true
So that the entire startup string looks like this...
(Don't type this in exactly. This is an example. There may be a difference between your computer and this depending on where you installed Java and TWS.)
C:\Program Files\Java\j2re1.4.1_01\bin\javaw.exe -Dsun.java2d.noddraw=true -jar C:\JTS\jts.jar C:\JTS
You also might try uninstalling TWS, downloading TWS again and reinstalling.

Ok, tell me the version of the Java runtime you are using, not the Web Start version. Unless you installed it elsewhere, it should be in C:\Program Files\Java. Inside the Java folder should be a folder named like this: "j2re1.4.1_03"
The name of this folder will be different on your computer of course. This tells you what version of java you are using. What is the version you have?
An alternative method is to open the Command Prompt window (DOS window) and type in java -version
Then hit return and it will tell you what version you have.
